Sony's goal for PS2 emulation in the PAL regions is 90% by years end. They are somewhere around 85% a the moment. No idea about the NA emulation. The PS1 emulation is close to 100% as far as I am aware.
Support for PS1 games on the PSN store depends on which region you are in. Japan has over 100 games while EU has about 10.
